Have been through this process with the local authority, did months of research and finally granted permission. Two garden rooms are now built, sat on a concrete base. They have a bedroom, lounge area and bathroom.
Max size you can have for these type of rooms is 6m wide, 26m deep, and 3m internal height (no restrictions on external height, or distance to the boundary). No standard building regulations apply, as they are classed as temporary structures. We built ours on-site using SIP panels, EDPM roof and cladding, and they are now connected to utilities, plastered and decorated.
The important part for us is that there was no planning application needed, nor does it rely on any permitted development rules for outbuildings. We are in a conservation area & greenbelt so we had lots of restrictions.
LA has been out to see the garden rooms now that they are finished, and is happy that they comply with the lawful development certificate.
Definitely recommend using this avenue if you have any restrictions on permitted development, or difficulty obtaining conventional planning permission for your project. Hope this helps.
